Idle problems

I have a 2005 wrangler with a 4 cyclinder 6 speed, when the air conditioner is running the engine dies when I stop. I am at a loss for what is going on. Can anyone help me out?

If it's still under warranty I would let the dealer do it. If not, see what the idle rpm is
with the air off. Then call the dealer and ask what the idle should be. It may be too low
causing the engine to die when a/c is on.

Yes, take it to the dealer since it's under warranty but my guess is the IAC (idle air control) that gives the engine all of its air at idle is dirty and sticking so the engine isn't getting enough air at idle. The IAC is mounted on the side of the throttle body and passes air for the engine to run on into the side of the throttle body when you are not stepping on the accelerator pedal.

When you have a choice, buy American.
